T-Mobile and AT&T versions

I'm thinking of getting a 'fully unlocked' S5 from an auction site. The seller has AT&T (SMG-900A) and T-Mobile (SMG-900T) versions available. Which is best? How do they differ from the international version apart from the printed logo and some carrier specific apps? Can they both be rooted?

The T-Mobile version has more bands of LTE support in the US. I am on ATT, and I bought a T-Mobile S5 a few days ago. I am loving the phone so far, and plan on getting it fully rooted and unlocked shortly. The international version that is sold doesn't have LTE band support. Both the ATT and T-Mobile versions can be rooted.

After using the G900A with AT&T (twice lol) I decided to pick up T-Mobile's S5 last Friday. Already running a custom rom and kernel. Love it. Only wish LTE reception was better optimized for AT&T's band 17.

That's incorrect. the ATT version cannot be rooted as of right now and has a locked bootloader. Definitely go with the Tmobile version if you want rooting and flashing ROMS
